Is that price painted or simply primed? In either case it's better than the original designers so you've definitely got my attention.

What I don't like about this one is that you have to fill in some of the holes from your original spoiler and drill new ones. I don't expect the thing to install itself but, filling holes and drilling new ones? That's a NO GO.

My only other suggestion would be to maybe incorporate a little bit of the dovetail spoiler into it so that the rear of the spoiler has a bit of a curve upwards. Not as dramatic as the dovetail but, just enough to give it an edgier look.

Hopefully, that makes sense to you. I'd draw it out or do a photoshop but, my talents lie in electronics and not in those areas. I leave that to you guys
